Thanks for the memory: More room for data in 'phase-change' material

By using diamond-tipped tools to apply pressure, a team led by Johns Hopkins engineers has discovered some previously unknown electrical properties of a common memory material, a mix of germanium, antimony, and tellurium called GST. The discovery should make GST more useful for electronics developers by allowing memory formats that retain data more quickly, last longer, and allow far more capacity.
